EarthVision Geostatistics Module

The EarthVision Geostatistics module provides 2D and 3D statistical methods for computing grid nodes based on 2D or 3D data, and incorporates the algorithms from Stanford University’s widely-used GSLIB geostatistics software library. Geostatistical models can be calculated conformal or non-conformal to structure, in selected zones and selected fault blocks of advanced structure models built with EarthVision’s powerful Geologic Structure Builder.

The Geostatistics module enables extensive pre-gridding data analysis to help optimize variogram model preparation prior to the kriging calculation. Variance grids can be calculated simultaneously with the estimate grid, and the spatial relationships of the data to be kriged can be analyzed using a number of different variograms and variogram maps, such as traditional semivariogram, covariance, correlogram, general relative, pairwise relative, logarithmic, rodogram, and madogram.

The EarthVision Geostatistics module offers a range of kriging algorithms, including:

• simple kriging
• ordinary kriging
• non-stationary kriging
• kriging with external drift
• kriging with a trend (universal kriging)
• collocated cokriging
